xfs: zero initialize highstale and lowstale in xfs_dir2_leaf_addname
Smatch complains about the following: fs/xfs/libxfs/xfs_dir2_leaf.c:848 xfs_dir2_leaf_addname() error: uninitialized symbol 'lowstale'. fs/xfs/libxfs/xfs_dir2_leaf.c:849 xfs_dir2_leaf_addname() error: uninitialized symbol 'highstale'. I don't think there's any incorrect behavior associated with the uninitialized variable, but as the author of the previous zero-init patch points out, it's best not to be passing around pointers to uninitialized stack areas.
